Learn to recognize these emotions in yourself and
othersKnow how you feel

Each emotion serves as a primal
beacon, guiding us along the difficult path
of survival and procreation. Many researchers have worked to define
emotions and have created their own lists of what they consider to be
an emotion. Several of those lists are presented here. Use these lists
and short descriptions to recognize the emotions you are feeling; then
use the detailed description of each emotion to guide you toward the
most constructive response. A subjective mood map
locates each emotion according to the energy level and good-bad
feelings often associated with it.

And Also:

It is likely that the variation and discrepancies among
these lists result from a
reification
fallacy. The abstraction that we loosely call emotion is
not real, it is not well-defined, and it most likely
describes a composite of disparate real phenomenon that are
not yet well understood.

Non-Emotions

In his 1991 book, Emotion and Adaptation,
Richard Lazarus lists several mental states that may be
emotion related, but are not themselves actual emotions. The
list includes the complex states of: grief and depression;
the ambiguous positive states of: expansiveness, awe,
confidence, challenge, determination, satisfaction, and
being pleased; the ambiguous negative states of: threat,
frustration, disappointment, helplessness, meaningless, and
awe; the mental confusion states of bewilderment and
confusion; the arousal states of: excitement, upset, distress,
nervousness, tension, and agitation; and finally the
pre-emotions of: interest, curiosity, amazement,
anticipation, alertness, and surprise.

Note he included awe and depression
in the list of emotions described in his later book, Passion
and Reason. Also, Paul Ekman includes surprise in his list
of basic emotions.

Other mental states, such as bored, alert, drowsy, and
trance are also not emotions.
